Haha, here's to another 500 then! And yeah, Grayson's announcement itself had pages on pages of discussion here, too. Also, let's not forget that while this is the main thread, many of post our main thoughts on each issue in their respective threads, so if we didn't do that, this thread would be even longer.
Also, in not as great news: There have been a lot of new DC figures announced, of which we get even more of "Batgirl of Burnside" and JimBats (Bunny suit and regular suit, too). But no Dick, no Grayson. Now, it's not like we would get a figure of Nightwing if Dick was still Nightwing, but the fact that we still haven't gotten a Grayson figure or merch of any kind really supports that we're going back to Nightwing.
Grayson's not getting any variants in May as well, but the only ones that are getting them are the #52s, so it makes sense. Still, if Grayson #20 is the end as many of us believe it is, it would have been cool if we had a cover referencing the New 52 Nightwing #1 cover, kind celebrating how far Dick's come since then, like a bookend thing.
